2M series styli are interchangeable within the below combinations: 
- 2M Red, 2M Blue, and 2M Silver
- 2M Bronze, 2M Black and 2M Black LVB 250
- 2M Mono and 2M 78

Special for 2M Red, 2M Blue, and 2M Silver phono cartridges:
- 2M Silver will be an upgrade compared to 2M Red due to a special suspension and silver-plated copper wire material.
- 2M Blue is an upgrade compared to both 2M Red and 2M Silver thanks to the Nude Elliptical diamond which retrieves information from the groove with a higher accuracy.
